Recipes rarely pop out of a chef ’s brain fully formed. They typically start with a little spark of an idea, and then comes the tinkering until they grow into something original and delicious, like pastry chef Rebekah Turshen’s buttermilk cornmeal cookies with sorghum marshmallow filling. “I usually have in my head what I want it to taste like and the texture and the visuals,” she says. “Then I just have to get there.”

Turshen landed her first baking job in 1993 while pursuing a graphic arts degree at the University of Mississippi. “It was kind of a fluke,” she says. But as it turned out, she liked making pastry better than graphic arts. After college, she continued to work in various Oxford kitchens. “I just started learning from books and magazines,” she says. “Because I was at small independent places and it was the 1990s, I could just work things out as I went.”

Since 2009, she has been an anchor at City House in Nashville, where her buttermilk cornmeal cookies were born. This time the spark came from New York pastry chef Christina Tosi’s Milk Bar, which started right around the time Turshen began working at City House. Tosi made a popular cookie with freeze-dried corn and corn flour. That got Turshen thinking about the skillet cornbread she grew up eating. “My mom and her dad liked to do that thing where they would pour the buttermilk over it and have it as a snack in a glass,” she says. Could she translate that into cookie form?

She figured out that medium-grind cornmeal offered the right texture for the cornbread nod she was looking for. For the buttermilk tang, she turned to buttermilk powder, common in Southern supermarkets. To add textural contrast, she mixed salt with sugar as a topping that bakes into a crinkly finish.

For years she had played with various recipes for the marshmallow filling, some of which required an acrobat’s timing. She eventually landed on a simplified method that makes it easier to incorporate sorghum-infused syrup into the whipped egg whites once it reaches the right temperature (the soft-ball stage in candy making). Vanilla, salt, and vinegar balance the marshmallow’s sweetness and give it more character.

If making marshmallow isn’t in your plans, the cookies are lovely on their own, especially with a cup of tea or a glass of milk. “I was trying to think about something you would want to come back for,” Turshen says. She nailed it. They went on the City House cookie plate as soon as she came up with them and have remained a favorite ever since.

MEET THE CHEF: REBEKAH TURSHEN

Hometown: Columbia, Tennessee

How to become a better baker: Bake regularly, and try out a handful of bakers’ recipes to learn different skills. “It’s all practice, repetition, and attention.”

Kitchen items she would grab if the house were on fire: Her new stand mixer and the cast-iron hamburger press from the truck stop her grandparents owned in Tennessee.

Why she’s a sucker for candy: “I like tasting all different cultures’ versions of sweets.” She also appreciates innovations from chef friends who specialize in candy making, like the Persian-inspired chocolate bars from Louisa Shafia in Nashville. (Coffee tahini and the crispy rice with saffron are her faves.)


Ingredients

  • Buttermilk Cornmeal Cookies with Sorghum Marshmallow (Yield: About 25 cookie sandwiches, or 50 single cookies)

  • For the cookies

    • 1 cup cool unsalted butter

    • 1 cup white sugar

    • ¾ cup light brown sugar

    • 2½ cups all-purpose flour

    • ⅔ cup stone-ground cornmeal (medium grind works best)

    • ½ cup sifted buttermilk powder

    • ¾ tsp. flaky salt, such as Diamond Crystal

    • ¾ tsp. baking soda

    • 2 large eggs

    • ¼ tsp. vanilla

    • ¼ tsp. apple cider vinegar

    • Cookie sprinkle: Mix together ¼ cup white sugar and ¾ tsp. flaky salt

  • For the sorghum marshmallow filling

    • 4 tsp. powdered gelatin (about 2 packets)

    • ⅓ cup cold water, plus ¾ cup water

    • 1 cup white sugar

    • 2 tbsp. corn syrup

    • 2 tbsp. sorghum syrup

    • 3 egg whites

    • ½ tsp. flaky salt

    • 1 tsp. vanilla

    • 1 tsp. apple cider vinegar


Preparation

  1. Make the cookies: Divide butter into 12 slabs. Add to bowl of electric mixer, along with both sugars. Using the paddle attachment, mix on medium-high for 5 minutes. The mixture should look uniformly cardboard colored and have a sandy texture. Scrape around sides and bottom of bowl, mix again briefly on high to incorporate any missed bits, and scrape one more time.

  2. Place flour, cornmeal, buttermilk powder, salt, and baking soda into a bowl and whisk to combine.

  3. Dump dry ingredients, eggs, vanilla, and vinegar over butter mixture. Starting with the lowest setting, mix until the flour begins to be combined, then turn the mixer to medium-high to fully incorporate everything. Turn to high briefly to finish.

  4. Scrape dough onto a floured board and shape into a rough 6x6x2-inch square. Divide into 3 strips and roll into 3 (10×1-inch) logs. Freeze for an hour or so to firm up. Slice logs into rounds about ½-inch thick and place 1½ inches apart on parchment-covered sheet pan. Sprinkle each cookie with ¼ teaspoon of the sugar-salt mixture.

  5. Heat oven to 350°F. Bake for 12 to 14 minutes. The cookies will be toasty around the edges and golden yellow toward the center. Enjoy as is or use marshmallow to make into cookie sandwiches.

  6. Make the filling: Put gelatin into a small, shallow saucepan. Add ⅓ cup cold water, and whisk together. Set aside to bloom while you make the syrup. The mixture will become translucent and firm.

  7. Combine ¾ cup water, sugar, corn syrup, and sorghum syrup in a small saucepan, stirring to combine. Over high heat, boil to 240°F using a candy thermometer (soft-ball stage), then immediately move off heat. Gently scrape bloomed gelatin into the syrup and mix gently.

  8. Whisk egg whites and salt on high in electric mixer. As soon as the whites turn opaque, with the mixer still running, drizzle syrup carefully into whites. Add vanilla and vinegar, whisking on high until whites hold shiny peaks.

  9. Make cookie sandwiches: While marshmallow is still warm, add a dollop to the center of the flat side of a cookie, top with the flat side of another cookie, and gently press so a bit of marshmallow peeks out. Let filled cookies set at room temperature for at least 30 minutes to firm up before serving.
